To report on a female patient diagnosed with Currarino's triad in adulthood. ⋯ In (young) patients with anorectal malformations, although having no other symptoms, further examination might be required to exclude Currarino's triad. Importance of early diagnosis and multidisciplinary assessment is recommended to establish adequate treatment if needed.

Subacute steroid-induced paraparesis: surgical treatment of a devastating "invisible" side effect.
To emphasize an underestimated side effect following long-term use of steroids. ⋯ Diagnostic work-up of such patients should include early spinal MRI resulting in surgical intervention, if indicated. Decompression of the spinal cord eventually combined with fusion is necessary.

Does hormone replacement therapy prevent lateral rotatory spondylolisthesis in postmenopausal women?
Degenerative scoliosis usually begins at menopause and lateral rotatory olisthesis (LRO) might be a triggering factor in the onset of degenerative scoliosis in postmenopausal women. We set out to evaluate the influence of hormone replacement therapy (HRT) on degenerative scoliosis and on LRO. ⋯ LRO was significantly lower in women who received HRT. The excess risk of LRO was dependent on both age and HRT status. These findings suggest that HRT might prevent the onset of LRO, and therefore might contribute to the prevention of low back pain.

Patients requiring anterior-posterior thoracic spine stabilization and suffering from concomitant cardiopulmonary disease are at increased risk to develop procedure-related complications. In order to reduce cardiopulmonary complications, the efficacy of a posterolateral transpedicular approach for 360-degree fusion was investigated. ⋯ The posterolateral transpedicular approach might be a safe, less-invasive and efficient alternative to anterior-posterior fusion. However, biomechanic efficacy and long-term outcome as compared to the transthoracic technique remains to be studied in a larger patient cohort.

The purpose of this study was to evaluate the influence of different implant designs of total lumbar disc replacements on the segmental biomechanics of the lumbar spine. The unconstrained Charité, the semi-constrained Prodisc and a semi-constrained Prototype with more posterior centre of rotation than the Prodisc were tested in vitro using six human, lumbar spines L2-L5. The segmental lordosis was measured on plain radiographs and the range of motion (ROM) for all six degrees of freedom with a previously described spine tester. ⋯ A more anterior centre of rotation in a semi-constrained prosthesis resulted in a higher increase of segmental lordosis after TDR than a semi-constrained prosthesis with more posterior centre of rotation. The location of the centre of rotation in a semi-constrained prosthesis did not alter the magnitude of ROM. Despite the different alterations of ROM and segmental lordosis due to implant design, these differences were negligible compared with the overall increase of ROM and segmental lordosis by the implantation of a TDR compared with the physiologic state.
